Schuyler Van Alen has never fit in at Duchesne, her prestigious New York City private school. She prefers baggy, vintage clothes to the Prada and pearls worn by her classmates. But when she turns fifteen, Schuyler's life changes dramatically. The death of a popular schoolmate haunts her in unexpected ways. And strangest of all, Jack Force, the most popular boy in school, is showing a sudden interest in her.

Once an outcast, Schuyler is thrust into Manhattan's most exclusive social circle. Its members are the powerful, the wealthy and - as Schuyler discovers - the unhuman. They are the Blue Bloods, an ancient group of vampires, and for centuries they've been invincible. Now something is preying on this elite group and Schuyler wants to find out the truth. But is she the most vulnerable of them all?
